User clicks extension icon → popup opens with spinner image and 6 design thumbnails → user clicks/drag on spinner to spin it → spinner rotates with physics-based deceleration → user can switch designs by clicking thumbnails

目标用户: Students / Office workers / People seeking stress relief or boredom relief / General Chrome users looking for a fun tool

The welcome page at freespeedcheck.net is not accessible from the source code, so we cannot confirm if that external site requires login or has paid features. However, the extension itself does not gate any features behind login or payment.
The extension redirects to an external homepage (freespeedcheck.net) on install, but this is a marketing/welcome redirect, not part of the core product workflow.

付费分析

未识别到付费功能

The extension is completely free with no paid features, no subscription gates, no payment integrations (Stripe, PayPal, etc.), and no upgrade prompts. The 'pro' keyword matches in static analysis are false positives: 'pro' in Czech locale means 'for' (pro Chrome) and in Slovenian means 'please' (Prosimo). No billing, license key, or premium feature gating code exists.

登录理由: The extension is a self-contained client-side fidget spinner tool. No login UI, no auth tokens, no calls to authentication endpoints, and no account creation flows exist in the source code. The background script only opens a welcome tab on install, but the core spinner functionality in popup.html/popup.js works entirely locally without any account requirement.
